crash on Alpha box

[Bohdan DURNOTA]

I am trying to install the new Swarm release on an Alpha
box. Have got through the install relatively unscathed
(although quite a few warning messages re. casting b/n
integers and pointers), and compiled the first demo - 
the heatbugs. But then when I tried to run, it seg faulted. 
I have included a dbx (Alpha debugger) trace [and also
a gdb trace] --- it is suggestive of a receiver object
not actually existing. However ... a bit stuck at this
point in time. Any help would be appreciated.

Thanks, Bohdan Durnota (Dept Comp Sci, Melbourne Uni)
